wtf is developer-skills?

developer-skills is an add-on for Claude Code, Anthropic's coding assistant tool, that lets you hand off an entire written specification for a feature and have a team of AI agents build it without you supervising every step. You write the spec, and the system breaks it into smaller pieces of work, builds each one, reviews the resulting code, fixes any problems, and merges it in, notifying you once everything is finished. The pipeline works in stages. A first agent looks at each piece of work and decides how complex it is, assigning it to either a faster or a more capable AI model depending on the difficulty. Then a separate agent actually writes the code for that piece in its own isolated copy of the project, so it never touches your main working files. Once a draft is ready, another agent reviews the changes and either approves them or sends them back for fixes, up to three rounds before a human is asked to step in instead of the loop continuing forever. By default, independent pieces of work are built at the same time rather than one after another, though the tool can be set to work through them one at a time instead. If you turn on an automatic merge option, approved changes are combined into the main project completely on their own, with the review step acting as the only checkpoint. Otherwise, finished work is simply marked ready and handed back to you to merge yourself. The full automated pipeline only works within Claude Code itself, since it relies on features specific to that tool, though some of its smaller building blocks also work with a tool called Google Antigravity. Installing it is done through a plugin command inside Claude Code, and it also depends on a separate, related toolkit for writing specifications and turning them into individual tickets, which needs to be installed and configured first. This is aimed at developers who already use Claude Code and want to delegate well-defined, spec-driven coding tasks to a supervised chain of AI agents rather than writing and reviewing every line themselves.
